In addition, object's position management department 230 positional information of also managing such immovable object in position in the Virtual Space such as building, trees, stone.
Wherein, RAM103 and CPU101 are as such object's position management department 230 performance functions.
The position of a plurality of performance cameras of hero role is faced in 240 storages of position of camera management department from different directions.
Particularly, position of camera management department 240 as shown in Figure 3, management is configured in the positional information of 3 performance camera EC1～EC3 in hero role SC the place ahead.Wherein, the direction (photography direction) of each performance camera EC1～EC3 is managed into when photography towards hero role SC.In addition, in Fig. 3, for convenience of explanation, the top view that utilization is looked down from the top represents the hero role SC the Virtual Space.In following accompanying drawing, also suitably utilize such top view to describe.
Positional informations of these performances camera EC1～EC3 can be the absolute positions that determines according to event, can be also the relative positions that the position according to hero role SC determines.
As an example of absolute position, in the situation that by the weapon that it is special that hero role picks up (acquisition), event occurs, be to be decided to be respectively with initial position (position of originally placing etc.) opposed 3 positions of this weapon etc.
In addition, as an example of relative position, in the situation that through the stipulated time (a time bomb exploded etc. such as set), event has occured, be to leave predetermined distance and opposed 3 positions etc. from hero role's current location.
Wherein, RAM103 and CPU101 are as such position of camera management department 240 performance functions.
Turn back to Fig. 2, differentiating obstacle section 250 is according to the positional information of each performance camera of storage in the positional information of each object of storage in object's position management department 230 and position of camera management department 240, differentiates respectively having or not of the barrier that blocks between each performance camera and hero role.
That is, differentiating obstacle section 250 is differentiated (whether EC1～EC3) exists the object that becomes barrier on the sight line VL of hero role SC from performance camera EC as shown in Fig. 4 A.
In addition, differentiating obstacle section 250 also can as basic point, use a plurality of auxiliary line of sight HL that consist of predetermined angular θ with sight line VL with performance camera EC as shown in Figure 4B, differentiates respectively on each auxiliary line of sight HL whether have object.Wherein, for convenience of explanation, represented the appearance that auxiliary line of sight HL only expands to horizontal direction in this Fig. 4 B, but in fact, auxiliary line of sight HL expands to vertical direction too.
In the situation that so used auxiliary line of sight HL, can also determine the situation etc. that barrier has blocked hero role's a part.
Wherein, CPU101 can be used as such differentiating obstacle section 250 performance functions.
Turn back to Fig. 2, camera list 260 records the information of being differentiated for the performance camera that there is no barrier by differentiating obstacle section 250.
For example, as shown in Fig. 5 A, in the situation that the barrier SB (situation that sight line VL1, VL3 are not blocked) of the sight line VL2 that has blocked performance camera EC2 is arranged, as shown in Fig. 5 B, store the information of performance camera EC1, EC3 in camera list 260.
That is, store the information that can not be subjected to barrier to take hero role's performance camera in camera list 60 with blocking.
Wherein, RAM103 can be used as such camera list 260 performance functions.
Turn back to Fig. 2, in the performance camera that camera selection portion 270 records, for example select at random 1 camera from camera list 260.That is, from being differentiated for selecting any 1 camera the camera that there is no barrier.
In addition, whole performance cameras also can occur differentiated for there being barrier, do not store the situation of any performance camera in camera list 260.In this situation, the distance of camera selection portion 270 selection hero roles and barrier is the corresponding performance camera of distance farthest.
For example, as shown in Figure 6A, supposed to occur the situation that sight line VL1～VL3 is all blocked respectively by barrier SB1～SB3 of performance camera EC1～EC3.In this situation, camera selection portion 270 as shown in Fig. 6 B, obtain respectively hero role SC and barrier SB1 apart from d1, hero role SC and barrier SB2 apart from d2, hero role SC and barrier SB3 apart from d3.Then, select and the performance camera EC3 corresponding apart from d3 that becomes maximum (far) distance.
In addition, also can occur in the situation that has a plurality of barriers on the sight line of performing camera.In this situation, the barrier close to hero role becomes the object of asking for distance.
Wherein, CPU101 can be used as such camera selection portion 270 performance functions.
Turn back to Fig. 2, camera control part 280 is controlled selecteed performance camera, performs with the photography action.
For example, camera control part 280 performance such as trucks up, pans, shakes with the photography action, takes to make the player gaze at hero role's the sporty image of tool.
Wherein, whole performance cameras is being differentiated for there being barrier, and in the situation of the distance of having selected hero role and barrier by above-mentioned camera selection portion 270 for farthest performance camera, camera control part 280 is performed the photography action of use making selected performance camera movement to than the rear flank of barrier near hero role.
For example, as shown in Fig. 7 A, under the state that performance camera EC1～EC3 is blocked by barrier SB1～SB3, selected distance performance camera EC3 farthest.In this situation, camera control part 280 is as shown in Fig. 7 B, to actual viewpoint (camera lens part in the figure) SB3 that clears the jumps, after can taking the position of hero role SC, perform the photography action of use at the position movement that will perform camera EC3.That is, performance camera EC3 is moved to the position of blocking and take as far as possible from afar hero role SC that is not subjected to barrier SB3.Then, begin to perform action from this shift position.
Wherein, CPU101 can be used as such camera control part 280 performance functions.
Turn back to Fig. 2, image is drawn section 290 according to the object information of storage in object information storage part 210 with by the role's of object's position management department 230 management positional information etc., draw the performance camera controlled with common virtual camera or by above-mentioned camera control part 280 as viewpoint, taken the game image of the object of (in the visual field) in the Virtual Space.
Particularly, in the situation that occured regulation event, selected 1 performance camera by above-mentioned camera selection portion 270, image is drawn section 290 and is drawn this performance camera that will be controlled by camera control part 280 as the image of viewpoint.
For example, in the situation that the performance that camera control part 280 is controlled is to truck up with the photography action, the viewpoint of virtual camera EC moves to position Y from position X as shown in Fig. 8 A.Therefore, image is drawn section 290 and is drawn the game image that the performance camera EC as shown in Fig. 8 B takes at X place, position, then, EC moves from X-direction position, position Y along with the performance camera, hero role SC is amplified (by trucking up gradually) gradually, finally draws the game image that the performance camera EC as shown in Fig. 8 C takes at Y place, position.
In addition, be pan or shake etc. in situation in performance action, also with above-mentioned same, image is drawn section 290 and is drawn with the position of performing camera with towards image corresponding to (viewpoint position and sight line).
Wherein, image processing part 108 can be used as such image and draws section's 290 performance functions.
(action of video generation device)
Fig. 9 means that the image of carrying out generates the flow chart of the flow process of processing in the video generation device 200 of said structure.Below, with reference to this figure, the action of video generation device 200 is described.This image generation processing for example in the implementation of game, when having satisfied the event occurrence condition of regulation, was carried out before this event handling.Wherein, when image generated the processing beginning, camera list 260 was cleared (without any record).
In game, when having satisfied the event occurrence condition of regulation, at first, video generation device 200 is set the position (step S301) of performance camera.
That is, set in position of camera management department 240 from the position of 3 different directions in the face of a plurality of performance cameras of hero role.That is, set and manage such and positional information opposed each performance camera of hero role EC1～EC3 as shown in Figure 3 above in position of camera management department 240.Wherein, the position of these performances camera EC1～EC3 as described above, can be the absolute position that determines according to event, can be also the relative position that the position according to hero role SC determines.
Namely, differentiating obstacle section 250 is according to the positional information of each performance camera of storage in the positional information of each object of storage in object's position management department 230 and position of camera management department 240, and differentiating respectively has unobstructed each performance camera towards the barrier of hero role's sight line.Then, information registration for the performance camera of clear will be differentiated in camera list 260 by differentiating obstacle section 250.
That is, record the information that can not be subjected to barrier to take hero role's performance camera in camera list 260 with blocking.In addition, blocked by barrier for whole performance cameras in the situation that differentiate, not login the information of any performance camera in the camera list 260.
On the other hand, in the situation that differentiate for not logining the information (step S303: no) of performance camera, video generation device 200 is obtained the distance (step S304) of hero role and each barrier.Namely, because whole performance cameras is blocked by barrier, so, shown in video generation device 200 Fig. 6 B described above like that, obtain respectively hero role SC and barrier SB1 apart from d1, hero role SC and barrier SB2 apart from d2, hero role SC and barrier SB3 apart from d3.
At first, in the situation that in camera list 260, login has the information of performing camera, camera selection portion 270 is 1 performance camera of random selection from this list.That is, from being differentiated for the performance camera of clear, select any one performance camera.In addition, in the situation that in camera list 260, the performance camera of login only has 1, automatically select this performance camera.
And in the situation that the information of login performance camera in camera list 260, camera selection portion 270 select with the distance of obtaining in the step S304 distance of each barrier (the hero role with) in maximum (far) apart from corresponding performance camera.For example, in the situation that shown in above-mentioned Fig. 7 A, select and the hero role performance camera EC3 that is blocked by barrier SB3 farthest.
That is, camera control part 280 is controlled selecteed performance camera, and beginning is such as the photography action of performance use such as trucking up.Wherein, do not login the information of performance camera in camera list 260, and selected in the situation of distance performance camera farthest of hero role and barrier, camera control part 280 with selected performance camera movement to than barrier near hero role's side after, begin to perform the photography action of use.For example, like that, clear the jumps and after can taking the position of hero role SC, perform the photography action of use to actual viewpoint (camera lens part in figure) at the position movement that will perform camera EC3 shown in Fig. 7 B described above.
Then, image is drawn section 290 and is drawn the game image of controlled performance camera as viewpoint.
That is, in the performance action of selected performance camera, differentiate whether there is new barrier between this performance camera and hero role.
In the situation that differentiate for there is no barrier (step S307: no), video generation device 200 makes to process and enters into step S310 described later.
On the other hand, in the situation that differentiate for there being barrier (step S307: be), whether the distance that video generation device 200 is differentiated hero role and this barrier is a reference value following (step S308).
For example, in the situation that the reference range in the Virtual Space is set as 1.5m, whether the distance of differentiating hero role and barrier is that this is below 1.5m.In addition, this reference range can be according to suitably changes such as the situations in game.
The distance that video generation device 200 is being differentiated for hero role and this barrier is not below a reference value, namely than a reference value large (far) (step S308: no), makes processing enter into step S310 described later.That is, control this performance camera, keep the photography action of performance use.
At this moment, camera control part 280 the position movement that will perform camera to just in the front of this barrier (viewpoint clear the jumps and can take hero role's position) afterwards, proceed the performance action.In addition, under the situation of being blocked for the moment moving due to barrier etc., also can not change the position of performance camera, proceed the performance action.Namely, when obtaining this barrier (object) in reference object location management section 230 and being motive objects and speed according to the rules (amount of movement) mobile (situations that the moving direction of barrier is different with the direction of visual lines of performance camera), the ground, position that camera control part 280 does not change the performance camera is proceeded to perform and is moved.
On the other hand, in the situation that the distance of differentiating for hero role and this barrier is (step S308: be) below a reference value, video generation device 200 is again performed the selection of camera and is processed (step S309).
That is, video generation device 200 carries out the processing identical with above-mentioned steps S302～S305, reselects the performance camera.
Whether the photography action that video generation device 200 is differentiated performance use finishes (step S310).
That is whether, differentiate trucking up of camera control part 280 waits performance to move to complete.
Under differentiating for the unclosed situation of photography action (step S310: no), video generation device 200 makes to process and turns back to step S306, repeatedly carries out the processing of above-mentioned step S306～S310.
On the other hand, be the photography action (step S310: be) that is through with in the situation that differentiate, video generation device 200 finishes the image generation to be processed.
Generate by such image and process, even exist under the situation of barrier, also can be from the performance camera of 3 directions, select rightly the performance camera that is not blocked by barrier and can take hero role and photograph.
In addition, even for example in the situation that whole performance cameras blocked by barrier, also select from the performance camera of hero role's barrier farthest, the performance camera movement to just in the front of this barrier (viewpoint clear the jumps and can take hero role's position), is taken hero role.Therefore, the performance camera can too near hero role, can not generate appropriate image.
As a result, even exist under the situation of barrier, also can generate and take rightly the image of wanting the hero role that gazes at.
